This series adds a defconfig for the STMicroelectronics STM32MP257F
Evaluation board (EV1), built from upstream TF-A, U-Boot and Linux, with
TF-A configured for the FWU (Firmware Update) multi bank support, as in
the official STMicroelectronics Yocto layers.

Unfortunately, it was not possible to use upstream OP-TEE OS as well,
because it does not support yet, on STM32MP25, the STPMIC2 PMIC and the
SCMI voltage domains, which the mainline Linux device tree requires for
the microSD card supplies [1]. Until this is resolved, the
STMicroelectronics downstream version has to be used.

Patches 1-5 add what the defconfig needs:

- the mkfwumdata host tool, to generate the FWU metadata, and the
  fwumdata target tool, to inspect and modify it from Linux (1-2);
- the STM32MP2 DDR PHY firmware, required by upstream TF-A, and a fix
  for the TF-A build of host tools (3-5).
